When You Need AC Replacement

Replacement isn’t about the age of the unit alone. It’s about what the unit is costing you in repairs, energy, and comfort. Here’s what we see most often in San Antonio homes before a replacement makes sense:

• Your system is over 12 years old and needs a compressor. A compressor failure on an older unit often costs $2,000 to $3,500 to fix. At that point, the math usually favors a new system with a full warranty.
• You’ve called for repairs twice in the same summer. In San Antonio’s heat, a system that fails repeatedly in July or August is telling you something. The second big repair is often the last one worth making.
• Your energy bills climb every summer while cooling stays weak. Older units lose efficiency as coils corrode and refrigerant lines wear. A new high-efficiency unit can cut cooling costs by 20 to 40 percent, especially in older North Side homes with original ductwork.
• Your system uses R-22 refrigerant (Freon). R-22 was phased out of production years ago. If your unit still runs on it, every recharge gets more expensive and harder to source. Replacement becomes the practical choice.
• Rooms are unevenly hot, no matter how many times you adjust vents. This often points to a unit that’s oversized, undersized, or simply worn past its ability to move air. A properly sized replacement fixes what repairs can’t.
• The unit is noisy, short-cycling, or leaking. Rattling, constant on-off cycling, or water pooling around the air handler are late-stage failure signs. In older San Antonio neighborhoods like Alamo Heights or Castle Hills, we regularly replace units that have been limping along for years.

Our AC Replacement Process

We built this process so you never stand around waiting and wondering. Here’s exactly what happens when you book a replacement with Halden Heating and Air San Antonio:

1. Book online or call (903) 623-6784. A real person answers, day or night. Tell us what your AC is doing (or not doing), and we’ll schedule a time that works for you.
2. Your tech arrives with a live ETA you can track. No four-hour windows. You’ll see who’s coming, when they’ll arrive, and when they’re pulling up to your door.
3. We assess your home and current system. Our technician checks square footage, ductwork condition, insulation, and your existing unit’s specs. We also ask about your comfort complaints so we size the new system correctly, not just swap like-for-like.
4. You get a written price before any work starts. We lay out your options, including equipment brands like Rheem, York, or Bryant, efficiency levels, and the total installed cost. You decide. No pressure, no door-step surprises.
5. We install the new system, usually in one day. Our crew handles the full swap: removing the old unit, installing the new indoor and outdoor equipment, connecting refrigerant lines, and verifying airflow. Before we leave, we take before-and-after photos and walk you through the new thermostat and system.
6. Your 365-Day Done Right Promise kicks in. Every replacement is backed by our written guarantee for a full year. If something’s not done right, we make it right, no argument required.

AC Replacement Pricing in San Antonio

We tell you the price before we do the work. Every time. Here’s what we see in San Antonio’s market:

Home Size / System Type	Typical Replacement Range
Small home or condo (1 – 1.5 tons)	$5,500 – $7,000
Mid-size home (2 – 3 tons)	$7,000 – $9,000
Larger home (3.5 – 5 tons)	$9,000 – $11,000+
High-efficiency or variable-speed upgrade	Add $1,500 – $3,500 to base range
Ductwork replacement (if needed)	Add $2,000 – $6,000 depending on home layout

What moves the number? Equipment efficiency level, home square footage, ductwork condition, and whether we’re doing a simple swap or a more involved install. A 1,400-square-foot home in Leon Valley will land differently than a two-story in Stone Oak with zoning needs.

How Much Does AC Replacement Cost in San Antonio?

Most full AC replacements in San Antonio run between $5,500 and $11,000 installed. That includes the outdoor condenser, indoor evaporator coil, refrigerant recharge and other labor, plus a new thermostat where needed.

Every Halden Heating and Air San Antonio quote includes the full installed price in writing before work starts, so the number you’re quoted is the number you pay. Call (903) 623-6784 for a free, no-obligation estimate.

Can You Replace My AC the Same Day?

In many cases, yes, we can replace your AC the same day or next day, especially during San Antonio’s brutal summer months when a down system is urgent. Our team keeps common equipment sizes and configurations in local stock, which speeds things up considerably. Call (903) 623-6784 as early as possible, and we’ll tell you straight what’s possible based on your home’s specs and equipment availability.

Is It Cheaper to Repair or Replace My AC in San Antonio?

The short version: if your AC is under 10 years old and the repair is under $1,500, repair usually wins. If it’s over 12 years old and the repair is a compressor or coil failure, replacement typically makes more sense. Here’s the math we walk through with San Antonio homeowners: a $2,500 compressor repair on a 13-year-old unit gives you maybe 2 – 3 more summers if you’re lucky. A new system at $7,000 spread over 15 years costs less per year, runs more efficiently, and comes with a full warranty. We’ll show you both options in writing and let you decide. For repair costs, see our AC Repair & Installation in San Antonio page.

FAQs – AC Replacement

How long does AC replacement take in San Antonio?

A standard AC replacement takes 4 to 8 hours for most San Antonio homes. Full system swaps with ductwork modifications or challenging attic access can run into a second day. We’ll tell you the expected timeline before work begins.

What size AC unit do I need for my San Antonio home?

The right size depends on square footage, ceiling height, insulation, window exposure, and ductwork condition. In San Antonio’s climate, most homes need roughly 1 ton of cooling per 500 to 600 square feet, but we run a full load calculation before recommending anything. Oversizing is just as bad as undersizing, it causes short-cycling and humidity problems, and we won’t do it.

Do you offer financing for AC replacement?

Yes, financing options are available for qualifying homeowners. We’ll walk you through the details during your estimate so you know exactly what the monthly cost looks like before you commit.

What happens to my old AC unit when you replace it?

We remove your old equipment and handle disposal, including proper capacitor replacement and refrigerant recovery, which is required by law and protects the environment. You won’t have a dead condenser sitting in your backyard. We haul it all away.

Will a new AC unit lower my energy bills in San Antonio?

In most cases, yes. A new high-efficiency unit can cut cooling costs by 20 to 40 percent compared to a 12-plus-year-old system, especially during San Antonio’s long cooling season from May through October. The exact savings depend on your old unit’s efficiency and the new system’s SEER2 rating.
